Let's hope Serbia tells 'the EU special envoy' to mind his own business.
As the Serb official in question, Alexsander Simic said:
"When someone fails to respect the Security Council, the only body that ought to react in times when there is a threat of aggression and war, particularly when someone does not observe Chapter VII of the United Nations Charter and the resolution that was adopted in line with it, then there is nothing else a country can do. Every state has the right to defend its sovereignty and territorial integrity by all means necessary,”

Serbia is faced with the illegal seizure of part of its historic territory, in blatant contravention of international law. Forget the imperialistic claptrap of the 'EU special envoy', Serbia has the right to self-defence, and use military means if necessary to prevent loss of its territory, as any country does. Let's hope that it doesn't come to that, but if war does break out, it will not be the responsibility of Serbia, but of the western countries who have, for their own selfish reasons, fomented separatism and discord in the region.
The ball is now very firmly in the court of the US and the EU. They can end their support for Kosovan separatism here and now, or they can plunge the region into a new war.
